Final answer:
Kentucky law requires a pass to be completed before reaching a solid yellow line, in a no-passing zone, or when it can't be safely and legally executed.
Step-by-step explanation:
According to Kentucky law, you must complete a pass before reaching a solid yellow line, a no-passing zone, or any situation where the pass cannot be made safely and legally. This means that when you are executing a passing maneuver on the roadway, you must ensure that you have enough space to pass the vehicle in front without speeding or causing danger to oncoming traffic. If an attempt to pass is initiated, it must be finished without interfering with the safe operation of vehicles approaching from the opposite direction.
